Design and realization of industrial online gas detector

Abstract

In view of the traditional gas analysis instruments working in low measurement precision, poor stability and single measurable components, this paper designs a multi-channel online detector used in industrial gas analysis. The multi channel makes people can use a variety of types of sensors, through different collocation, to measure the different gas composition. System part selects the industrial-grade STM32F407 chip as the core of the detector to analysis and process the signal，with the new digital infrared sensor S-Module as the main means of detection. In addition, it can integrate the detection and recording by means of intelligent. The results show that the gas detector has the characteristics of good stability, high measurement precision and strong anti-interference ability, which can meet the basic requirements of industrial field gas concentration detection.
